Objective:
Allergic rhinitis can cause symptoms to worsen after pregnancy and may cause problems such as postpartum depression. The goal of this study was to investigate the factors that influence postpartum depression in pregnant women with allergic rhinitis (AR).
Methods:
We conducted a retrospective cohort study that included women with AR (based on self-reports) between June 2015 to June 2019 in Harvard University Partners Healthcare Systems (PARTNERS) in the USA. The study group was divided into postpartum depression and non-postpartum depression. Routine clinical and laboratory information was collected. Univariate and least absolute shrinkage and selection operator (LASSO, employed for predictor selection) regression analysis was used to study associations between AR during pollen seasons and adverse outcomes. Additionally, the receiver operating characteristic (ROC) curve evaluates discriminative ability by the area under the ROC curve (AUC). The calibration curve (DCA) was conducted to determine the clinical utility and benefit of the nomogram.
Results:
A total of 216 pregnant women with AR participated in this study. Univariate analysis showed that 7 indicators were significantly different (P < 0.05). LASSO and multivariable regression identified four predictors to construct a nomogram for PPD in pregnant women with AR, the four selected risk predictors are as follows: pollen season pregnancy (OR = 1.514, 95%CI: 0.771-2.973), history of preterm birth (OR = 2.723, 95%CI: 1.157-6.406), number of pregnancies (OR = 2.104, 95%CI: 1.356-3.267), anti-allergy medication during pregnancy (OR = 2.975, 95%CI: 1.521-5.819). The nomogram displayed good discrimination, with AUC of 0.732 (95% CI: 0.657-0.808). The risk of postpartum depression increased with the increasing risk score of predictive nomogram. The calibration curve and DCA present optimal predictive power.
Conclusions:
We highlighted the comorbidity of AR and postpartum depression, and suggested that a multidisciplinary consideration between allergists and obstetricians or midwives is needed to ensure that pregnant women consult experts to reduce AR symptoms.

Asthma-I: Introduction
Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Stress and Mental Health
